The body had been there at least overnight, according to the Anoka County sheriff’s office.

The snowmobiler was traveling west across the Coon Lake channel and hit a tree on the shoreline. Based on the damage, authorities estimated he had been driving very fast and he didn’t appear to be wearing a helmet.

Authorities identified the victim as Corey Glen Watson, 32.

The sheriff’s office and the Midwest Medical Examiner’s Office are investigating the incident.
